To all whom it may oonaem:

Be it known that LWILL B KNAPB, a citizen oi the United States, residi' at Salt Lake Citg, .in the county of salt iake and State of tahhwe invented a. new and useful 1m movement in Fluid Motors; of which the owing is La :ecifieation. I

This invention .rzfates ho fluid motors for driyingrotary tools, or .zfior other purposes, its object is :to simplify and improve the strunture whereby ,a oheeply constm oted means may be momma, which ma; he need form, vwmeqy of punposes, and wine will attain the end In an efiicienlt manner;

in carrying out-the invention, hhereis provided B.*I' t0 1'- having 'paeklles 50 he to constitute .a. zpomer wheel which :ie-cepahie of being impelled by-vweter, :conipressed air, or efieaznyan inlet duct being apwvicled in staingential relation 50 as mouse the fluid to the :blmiesv $11? an ppnoprlaite angle, and a eu'ardor segmenbal plate lying at one Side of mind some of the blades, whereby :fiuid entering the casing llllrmifih the inlet vduet is=eonstmined to remainin e orfion of gthe'mtor overed lay the guard. muis'ion is also made ior mounting the on bhe intelimediate orfrion 20f the --clriving shaftfwhereby he ends of :ohe

shaftmay be utilized for delimering the whichxth'e casing-oontaiiningitherobor is .provail'ed with n. detachable heed, and saidhead' carries the discharge duet :for the escape :of efli fluidlaffier :it-hasected upon thelfltOI'. "The invention will :be "best understood :Erom a consideration .of'the following deataileel description in eonnecbion with the accom anying drawing forming part; 1f this .speeiiicatien, with -the understanding, however, that the-invention is not confined to my strict 'con fonmity :with the showazng in the drawing, but me: he changed and modifieclrso long :ae-such-c' an'ges and modifications mark :no material 'dBPmLlP-B from the salient featunesnfithe invenfiion as ezppressed in the appended elei ns. the-drawings:

Carried by the heo'cl end Qof-the casing l is an elongated container-7, containing a, -0- tary shaft 8 having n snow-threaded termination 9 extending through a journal hearin? 10 in the container 7 a-nd'axial to the oy indrical casing 1. The 'ournal hearing 10 forms a stop or abntment I or a. bevel gear 11 fastlto theshaft 8 and meshing with another bevel ear H2, on a palmtershnft SL3 having bearings 1 4=, 115 Within the co tainer 7, with the oountersha f t' 13 at the end remote from the be vel gea nm, provided with aecrew-tln eacled termination 16, for the reception of -a,not;her'sheib 1-7, screwed onto the sliaft 18 and contitutixig a shgvft filirough which power may -be transmitted from the shaft 8 to some point of ntilizationof power.

The shaft 8 extends through the-head 2, into -I:he casing 1 end there carries a disk 18 with a marginal rim 19 in the form of a flange inset with relation to the periphery of the disk 18, and {he disk between the finnge 19 and -the= eriphery thereof'is pro vided with a, circu 11; series of blade: 20 at a sufficient angle "to Tadll of the disk "18 to constitute impeller blades whereby fluidunder pressure may be Ioyed =to cause roteti on of-tiho disk H3, -so fhet suehplilte =wi'fih it blades serves the puz pose of e; propeller or power wheel.
